001 — Ingredients

Five things.
Nothing else.

Most ready-to-drink protein hides behind a paragraph of additives. Read the label. If you can’t pronounce something, we didn’t use it.

  1. 01

    Brewed black tea

    Whole-leaf assam, cold-brewed for 14 hours so it pulls flavor without bitterness.

  2. 02

    Cold-pressed mango

    Ataulfo mangoes — the small honey ones — pressed and pasteurized within 24 hours of harvest.

  3. 03

    Valencia orange

    Juiced with the pith on, which is where the bitter-citrus aromatics live.

  4. 04

    Whey protein isolate

    Sourced from a single dairy in Wisconsin. Cross-flow microfiltered, never heat-denatured.

  5. 05

    Sea salt & lemon

    A pinch of salt and a squeeze of lemon to round the finish. That’s the whole formula.

002 — About

We made the drink we couldn’t find.

Kalo started in a small kitchen in Oakland in 2024. We’d spend mornings at the gym and afternoons at our desks, and we never found a drink that fit both. Shakes were heavy. Protein waters were medicinal. Iced teas tasted nice but did nothing.

So we made our own. The first batch was brewed in a French press, cut with mango juice, and shaken with a scoop of whey we ordered from a dairy co-op in Wisconsin. It wasn’t perfect, but it was the first one we’d finish without thinking about it.

Two years and a few hundred batches later, this is what we landed on. One flavor. Real ingredients. The label fits on the bottle because there’s not much to hide.

“We wanted a drink that earned its place on your desk without asking you to think about it.”

003 — Questions

Reasonable
things to ask.

Is there really only one flavor?
For now, yes. Mango and orange were the first combination we couldn't stop drinking, so we shipped that one first. A second flavor is in testing for late 2026.
What kind of protein is this?
Cross-flow microfiltered whey protein isolate from grass-fed cows. No hydrolysates, no concentrates, no plant blends mixed in.
Why does it need to be refrigerated?
We pasteurize but don't sterilize. Keeping it cold preserves the brewed-tea aromatics and the natural fruit flavor — both of which die under heat.
Where can I buy it?
Through this site at launch, and a handful of independent grocers in the Bay Area. We'll expand from there once we get the cold-chain logistics right.
